A 64-year-old woman who had amyotrophic lateral sclerosis (ALS) with disturbance of vertical ocular movement was presented. She was admitted to our hospital with progressive dysphagia, dysarythria and weakness of the extremities. Neurological examinations revealed disturbance of vertical ocular movement with normal doll's eye phenomenon (supranuclear origin), bulbar palsy, muscle weakness of the extremities, extensor plantar signs, and fasciculations of the costal and interosseal muscles. EMG studies showed denervation potentials, and muscle biopsy demonstrated group atrophy, fiber type grouping and small angular fibers. TRH injections resulted in improvement of disturbance of vertical ocular movement, but no effect was seen on the weakness of the limb. There was about 20 Japanese cases with disturbance of ocular movement in ALS, but it was rare to see ocular movement disorder from the early stage of ALS. The pathophysiology of ocular movement disorder in ALS has been thought to be due to supranuclear origin, i.e., the disturbance in the pathway from the frontal cortex to the mesencephalon. In this case, TRH might effect at some point of the frontomesencephalic pathway.

An 11-year-old girl with diffuse goiter is presented. She had no clinical evidence of thyrotoxic symptoms or signs of palpitation, excessive sweating, tachycardia or finger tremor. Both the serum T4 (24.0 micrograms/dl) and T3 (282ng/dl) were high, and thyroid 131I uptake rate (63.2%) was significantly elevated, but T3/T4 ratio was not elevated (11.8). BMR was measured three times and remained within normal limits. Her serum TSH was 1.9 microU/ml, and a TRH stimulation test resulted in a normal rise of serum TSH (13.4 microU/ml). The TSH secretion was not suppressed by medication (p.o.) of 75 micrograms of L-triiodothyronine given for 8 days. The autoantibodies of T4, T3 and TSH were negative. No sign of pituitary tumor was observed by plain X-ray film. No defect in her sight-field was found. From these clinical figures and data, Refetoff's syndrome was suspected. She was eumetabolic without any treatment, but the goiter gradually enlarged and dysphagia developed. A large dose of L-thyroxine (450 micrograms/day) was given for a period of one year and four months. She has been eumetabolic. Her goiter disappeared and the dysphagia completely subsided. After she was given large doses of L-T4, her serum TSH was reduced to 0.07 microU/ml and was slightly elevated to 0.24 microU/ml at 30 min after i.v. infusion of 500 micrograms TRH. Thyroid 123I uptake rate was suppressed to 8.3%. According to Refetoff's papers, this case was classified as being in the group with generalized resistance to thyroid hormone.

We report a case of chronic progressive external ophthalmoplegia with pituitary hypothyroidism. This patient had complained of hearing-loss at the age of fourteen and loss of body weight at fifteen. She was examined by otorhinolaryngologists at large hospitals yearly over a period of 5-6 years, but hearing-loss remained unknown. As her ophthalmoplegia progressed (as is evident from family photographs from the age of sixteen onward), with hindsight it should have been recognized. When examined on October 11, 1991, she complained of ptosis, speech disturbance and dysphagia at the age of thirty-four. Neurological examination revealed limitation of ocular movement, bilateral ophthalmoplegia, facial muscle atrophy, and weak gag reflex. She showed muscle atrophy in her neck including both sternocleidomastoid, major and minor rhomboid, girdle and distal parts of upper and lower extremities. Muscle biopsy of her biceps demonstrated ragged-red fibers, cytochrome c oxidase (CCO) deficient fibers and deletion of mitochondrial DNA. A plain CT scan revealed bilateral periventricular lucency, and a brain MR image showed a normal sized pituitary gland but diffuse high-signal intensities in the both periventricular white matter with proton density weighted and T2-weighted axial MR image. And also her electroencephalogram showed diffuse 7 Hz slow waves in all areas and increased slow waves by hyperventilation, and all waves from I to V of the auditory brain stem response disappeared. The effect of TRH on serum TSH secretion was not evident in this patient. This case was ascertained to be chronic progressive external ophthalmoplegia with pituitary hypothyroid function.

We report a 63-year-old man who died of respiratory failure. He was well until 1992 (57 years of his age), when he had an onset of progressive weakness of the bilateral upper limbs. He showed no improvement with TRH administration in other hospital. On January 12, 1994, he admitted to our department because of the progressive muscle weakness. Neurologic examination revealed a muscular atrophy associated with severe weakness and hyporeflexia in both upper limbs, and fasciculation were seen in his tongue. Electrophysiological studies revealed mild conduction block in the left medial nerve, and F-waves were not evoked in the left ulnar nerve and bilateral median nerves. After an administration of 25 g/day of human gamma-immunoglobulin for 5 days, conduction block as well as F-wave abnormalities in the left median and left ulnar nerve were improved, yet no improvement of muscle weakness was seen. The anti-GM1 IgG titer was transiently elevated in the patient's serum after gamma-immunoglobulin therapy. On September 8, 1994, subtotal gastrectomy was performed because of the early stage gastric cancer. Histological examination showed poorly differentiated adenocarcinoma (signet-ring cell carcinoma). His muscle weakness had been gradually extended to the lower limbs and he couldn't walk himself on January, 1998. On March, 1998, he developed tetraplegia, mild dysphagia, dysuria and the respiratory disturbance. On April 12, 1998, he admitted to our department for the second time. Neurologic examination revealed a muscular atrophy and fasciculation associated with severe weakness in all of his limbs, tongue and musclus masseter. Neither deep tendon reflex nor pathologic reflex was evoked in his upper and lower extremities. His ocular movements and sensations were well preserved. He died of respiratory failure on May 1, 1998. The patient was presented in a neurological CPC. Neurological and laboratory findings suggested a spinal progressive muscular atrophy (SPMA). However, there were several unusual points as a typical SPMA in this case, that is, an improvement of the electrophysiological abnormalities by gamma-globulin treatment, as well as transient elevation of anti-GM1 antibody. The clinical neurologists have arrived at the conclusion that the patient had lower motor neuron syndrome associated with anti-ganglioside antibody and cause of death was ascribed to the respiratory failure. We discussed whether this case was SPMA or multifocal motor neuropathy. Postmortem examination revealed numerous diverticulums in the ascending colon and lymphothyroiditis. No recurrent carcinoma was detected. Neuropathologically, both severe atrophy of the anterior spinal roots, and severe gliosis and neuronal loss in the anterior horn of the spinal cord were observed. Onuf nuclei were not affected. Neurogenic muscular atrophy was detected in the tongue, diaphragm, and limb muscles. Motor neurons of the brainstem were relatively preserved, but skein-like inclusions as detected by anti-ubiquitin antibody, were present in the facial and hypoglossal nuclei. Neither motor cortex nor cortico-spinal tracts were affected. Demyelination, remyelination or cellular infiltrations were not apparent in the right median nerve and sciatic nerves. The neuropathologic features were compatible with SPMA.
